Adefovir Impurity 12 CAS 20245-85-6 chemical structure

Description

As a certified reference material (CRM), Adefovir Impurity 12 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Adefovir Impurity 12 (CAS 20245-85-6) is a certified pharmaceutical impurity reference standard with the molecular formula C7H7N5 and a molecular weight of 161.16 g/mol.

Based on its molecular formula C7H7N5, Adefovir Impurity 12 contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 161.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
